MESNE ASSIGNMENTS, TO INTER- NATIONAL CHEMICAL COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

VAPORIZER FOR DISINFECTANTS.

To all whom it may concern:

Be it known that I, GEORGE 'LEININGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vaporizers for Disinfect ants; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to improvements in generators, and particularly to formaldehyde generators.

The object of the invention is the provision of means for facilitating the generation of gas from solidified formaldehyde.

\Vith this and other objects in view, the invention consists of certain other novel constructions, combinations, and arrangementsof parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the claim hereto appended.

In the drawings: Figure 1 is a view in side elevation of a generator constructed in accordance with the present invention. Fig. 2 is a view similar to Fig. 1, showing the stand in vertical, central section. Fig. 3 isa view of another embodiment of my inven tion shown partly in side elevation and section. Fig. i is a vertical, central sectional view of the stand and showing the receptacle and lamp in side elevation, of another embodiment of my invention.

Referring to the drawings by numerals, 1 designates preferably a cylindrical stand, constituting the body of the generator. The

Specification of Letters Patent. Application filed. August 22, 1905. Serial No. 275,304.

cylindrical stand is provided with a base 2 a 1 and with an openlng at lts front, which pef- 1 mits of the positioning of a lamp 3 within said stand. The lamp 3, constituting heating means, is supported within the stand upon a depending, annular flange 4, substan tially L-shaped in cross section. The burner E 30 of the lamp is provided with a dished deflector 31, which prevents the soot which accumulates on the semi-spherical bottom of the generator from dropping into the filling g A handle 5 is secured. 2

ears 6, 6, which are secured to the side of the stand 1.

The receptacle of the generator comprises a cylindrical body 7 and a semi-spherical bottom 8. The upper edge of the bottom 8 is of less diameter than the cylindrical body, thereby forming a shoulder or bead 9. The upper edge of the body 1 engages the annular shoulder of the receptacle and produces astructure which, when the receptacle and stand are assembled, resembles an integral structure, as the thickness of the wall of the stand is of substantially the same as the width of the shoulder. The cylindrical body 7 of the receptacle converges at 10 and terminates in a beaded edge 11. It will be obvious that the receptacle is provided with a reduced, upper portion, which produces an aperture of less diameter than the cylindrical body portion '7.

In the embodiment depicted in Fig. 3, the stand 12 is constructed similarly to the stand 1 with the exception that the base 2 is provided with a horizontal flange 13, constituting a support for a lamp 141. In the embodiment depicted in Fig. 2, the flange 4 depends from the stand which is not true of the flange 13.

As shown in Fig. 2 the bottom of the stand 1 is open and is provided with an angular flange having an inner horizontal portion 4 and an outer horizontal portion 4 and also having an intermediate vertical portion 4 whereby when the lamp is in- 5 sorted through the enlarged opening in the side of the stand the horizontal portion 4 permits of a space being provided on the inner surface of the and bottom wall of the lamp will contact respectively with the vertical portion 4 and horizontal portion 4 of the angular flange 4:.

. The receptacle in this embodiment is of similar structure to the receptacle depicted in Fig. 2, except that a portion of the side of the receptacle is pressed outwardly for forming an integral, annular shoulder or bead 9 which normallyengages the upper edge of the stand 12 for supporting the receptacle. shoulder is formed intermediate the semispherical bottom 15 and the cylindrical body 16. Each of the stands 1 and 12 is provided stand so that the side It is to be noted that this annular downward and passes receptacle is with ventilating openings 17, which are formed near the bottom of the stand and contiguous to the lamp. comparatively small openings 18 are formed in the stands near their upper edge, or end.

Owing to the semi-spherical structure of the bottom of the receptacle, the flame from the lamp, or any suitable heating means, is permitted to play over a comparatively large area of the bottom of the receptacle, as compared with a receptacle provided with a flat bottom. The heat from the lamp, owing to the structure of the bottom of the permitted to pass up between the inner wall of the stand and the outer wall of the bottom of the receptacle near to the annular shoulder, and thence it returns out of the openings there will be some of the heat passed between the bottom of the receptacle and the stand and above the openings 18, which eventually is discharged through the openings or apertures. The stand 12 is provided with an apertured ear 19, upon which is removably secured a straight handle 20.

In Fig. 4, I have shown a stand which 18. That is to say,

" comprises angular legs 21, which are preferably formed of sheet metal, the legs being connected at their upper end by means of a ring 22, and near their lower end by a similarly constructed ring 23. Each of these rings is provided with a horizontal portion which is integral with a vertical, depending portion. A lamp 24 is removably position, and also an intermediate vertical portion, the outer horizontal portion of the flangeadapted to permit of a lamp being inserted through said enlarged opening so that the side portion and bottom of the lamp will contact respectively with the vertical. and inner horizontal portion of said flange, a generator removably connected to the top of the stand and having a hemi-spherical bottom projecting downwardly into the same, said stand'having a series of inlet openings arranged around the lamp, and also having a series of outlet openings arranged around the bottom of the generator. and a dished deflector on said lamp adapted to receive the accumulation of soot from the hemi-spherical bottom of the generator.
